You should get a log that looks like this (line numbers will vary)
153 data test1;
NOTE: The data set WORK.TEST1 has 1 observations and 1 variables.
NOTE: DATA statement used (Total process time):
real time 0.01 seconds
cpu time 0.01 seconds
Now try this:
If that runs okay then the system is working and will access a properly formed data set.
So I would go back to your source for those data sets. They may be corrupted or not actually SAS data sets at all. The message you are seeing about "0 columns" means that when SAS is attempting to use the data set it reads header information about the contents of the data set such as the names and types of variables. 0 columns means that no variables are found. I downloaded all 4 of those files and none of them show having any variables or observations (rows)in them. The file size in my Windows setting of 5K is just about the minimum for a text file with only one character in it. Interesting is that they also all show a creation/modified date of 14Aug 2008.
I strongly suggest going back to what ever source of these files and examine things like the file size as they appear to have been corrupted/empty for a very long time.
